Production of important production processes for automotive high-voltage cables

The layer of insulation in the conductor of the high-voltage cable used in new energy vehicles is referred to as the core, which is made by twisting multiple cores into a single strand at a specified stranding distance and direction, and wrapping a layer of wrapping tape at the same time. The so-called core, core stranded products called cable, is one of the important processes in the production of stranded multi-core cable.

Core stranding technology requires the following requirements.
Stranding and bundle the same principle, are the same stranded direction of a one-time bundle into a core wire.

Stranding process, the direction of cable formation should be the right direction, as is known. Steel strip should be double leftward gap wrapping, wrapping gap is not greater than the standard of the width of the steel strip, and the gap of the inner steel strip should be covered by the middle part of the outer steel strip, the outer steel strip overlap the width of the inner steel strip should not be less than the standard of the width of the steel strip.

Core wire arrangement: first of all, according to the customer's requirements, the requirements of the core wire must be arranged according to the drawings.

Filler, the common fillers are: tear rope, cotton rope, PP rope... Filler, etc. can be twisted with the core wire at the same time.

Application: High voltage cables for automobiles connect charging ports and batteries, inside batteries, battery and engine components, and battery energy storage devices. Cable characteristics: As a carrier for power transmission. Due to the connection of high-voltage equipment inside the vehicle, automotive high-voltage cables have very high performance requirements. Including wiring space is small, high current and high voltage, high and low temperature environment more heat dissipation is not good, etc. Automotive cables should have salt spray and electromagnetic field, with oil and chemicals, have low smoke and halogen-free flame retardant and other environmental protection and safety requirements. There are environmental protection and safety requirements such as low smoke and halogen-free flame retardant.
